[Laszlo-dev] changeset 36594: make proxied data loading use Flash XML parser instead of swf-encoded binaries

[P T Withington]

Very cool.  Is now the time to try the experiment of data inheriting  
from the built-in class?  It may take a little work, but look at  
debug/LzMessage for an example where I subclass String.  Basically I  
had to over-ride all the built-in methods to make it work, because I  
think the built-in methods take shortcuts (essentially they are  
`sealed` and don't work for sub-classes, although you just get odd  
behavior, not an error).  Still I think it could be worthwhile to  
save copying the data.
